The total number of lemon candies is 1, solved using the linear equation in one variable 3l + 12 = 15, where l is the number of lemon candies.
We assume the number of chocolate candies to be c.
We assume the number of vanilla candies to be v.
We assume the number of peppermint candies to be p.
We assume the number of lemon candies to be l.
The total number of candies is given as 15.
This can be represented by the linear equation: c + v + p + l = 15 ... (i).
The number of peppermint candies and lemon candies together is given to be twice the number of chocolate and vanilla candies together.
This can be represented by the linear equation: p + l = 2(c + v) ... (ii).
There are eight more peppermint candies than lemon candies.
This can be represented by the linear equation: p = l + 8.
Substituting p = l + 8 in (ii), we get,
l + 8 + l = 2(c + v),
or, 2(l + 4) = 2(c + v),
or, c + v = l + 4.
Substituting c + v = l + 4, and p = l + 8, in (i), we get:
l + 4 + l + 8 + l = 15,
or, 3l + 12 = 15,
or, 3l = 15 - 12 = 3,
or, l = 3/3 = 1.
Therefore, the total number of lemon candies is 1, solved using the linear equation in one variable 3l + 12 = 15, where l is the number of lemon candies.
